Question 9 Which of the following would have the highest mass?
A
0.75 mol CO3(PO4)2
B
1.2 mol Fel2
С
10 mol CH3C1
D
17.5 mol Cl2

A. 3 mol  3 mol Al:

Explanation:

Te given balanced chemical equation is :

According to the stochiometry :

A: 3 mol  3 mol Al:

3 moles of chlorine reacts with 2 moles of aluminium

B. 2 mol  3 mol :

2 moles of aluminium  reacts with 3 moles of chlorine

C.  2 mol  2 mol Al

2 mol of aluminium produces 2 mol of  

D. 3 mol  2 mol  

3 moles of chlorine produces with 2 moles of  

Thus the conversion factor not used for mole to mole calculations is  3 mol  3 mol Al:

Explanation:

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
